摘要： Methods and systems are provided for diagnosing each of a plurality of engine cooling system components including various valves and grill shutters. Each valve may be individually closed and opened for a specified duration, and corresponding changes in coolant temperature may be monitored. If all the components are functional, the various valves may be adjusted to stagnate coolant at the engine and expedite engine warm-up during a cold-start.

摘要： Systems and methods are provided for monitoring reverse flow of fuel vapors and/or air through a vehicle fuel vapor recovery system, said fuel vapor recovery system coupled to an engine intake of a boosted internal combustion engine. One example method comprises, during boost, when the fuel vapor recovery system is commanded to be sealed from the intake, indicating degradation based on a pressure value at a venturi in the fuel vapor recovery system.

摘要： Methods and systems are provided for expediting engine system heating by stagnating coolant in one of a plurality of loops in an engine cooling system. Degradation of the various valves and thermostats of the cooling system can be diagnosed by adjusting the valve and monitoring changes in one or more of coolant temperature, transmission temperature and cabin temperature. Based on engine operating conditions, the various valves may be adjusted to vary coolant temperature in different regions of the cooling system, thereby providing fuel economy benefits.
